This is the Python mode for Tom Betherston's Alpha 6.5 text editor on
the Mac.  Contributed by Robin Friedrich <[email protected]>

From the readme, it supports:

Extensive keyword colorizing, plus menu and keyboard shortcuts to
facilate the writting of python code.

Cmd-Dbl-Clicking of certain terms in source will open and scroll to an
explaintion of that term in the help document: "Python Commands".

Saving of a file in Mac format with a "Pyth" creator code when you
save a Python document via the cmd-s keyboard shortcut ("Save" from
the File menu is just a regular save).
